The Kiwi Fertiliser Way

At Kiwi Fertiliser our major focus is building and maintaining fertility on as many farms and horticultural properties as possible, New Zealand wide.

We exist because some of the fertiliser companies have failed to deliver real fertility to farmers, who demand and deserve better treatment.

We knew there had to be a better way, so we asked Kiwi farmers what they really wanted from a fertiliser company, and they told us:

  • For a working relationship to be fostered on trust and accountability
  • To be listened to and shown respect for what each individual farmer is trying to achieve
  • To meet the requirements of increasing profit while minimising the environmental footprint
  • To be multi-dimensional, not just focussed on one aspect of soil fertility

And that is what we at Kiwi Fertiliser are delivering every day, all over New Zealand. We are absolutely committed to changing the face of New Zealand agriculture for the betterment of farmers, growers, and the environment.

We pride ourselves on delivering fertility that is as close as possible to what nature intended, while balancing the commercial reality, and providing information and advice that farmers and growers can literally bank on.


our approch 01

Our approach is based on the Albrecht-Kinsey system of soil fertility

Many farmers in New Zealand and in 75 countries around the world are actively growing their production and profit by using the Albrecht-Kinsey system of soil fertility. Currently we have five years of solid results behind us that has proved to us that this system works exceedingly well here in NZ. The Albrecht-Kinsey system is backed up by 80 years of science, and by results that speak for themselves.

Making a difference to your farm

  • Properties we fertilise can produce higher yields of higher quality pasture, lucerne, kale, sorghum and many other crops.
  • The nutrients are in the plant, in an organic form, and therefore exactly where they should be and not in the soil in a leachable form or, worse still, in the water.
  • The health of those crops is transferred to the animals consuming them, leading to lower veterinary costs.
  • We do not stop with NPK. All nutrients are addressed as necessary.
  • All the political boxes are ticked, as carbon sequestration is a given when soil fertility issues are addressed correctly.

The message is clear: Superior results that transfer directly into greater profitability and sustainability on the farm.

The founders of the Albrecht-Kinsey system of soil fertility

Neal Kinsey runs Kinsey Agricultural Services, which specialises in building and maintaining soil fertility for optimum quality and yields. As a consultant, Neal Kinsey’s job is to advise those who want guidance on how to improve their soils, crops, pastures and animals, so the clients’ production targets are better achieved. Neal Kinsey studied soil science under Dr. William Albrecht, Emeritus Professor of Soils and former Chairman of the Department of Soils at the University of Missouri; College of Agriculture.

Dr. Albrecht was born on a farm in Illinois. He grew up with an intense interest in the soil and all things agricultural. As he and his associates unlocked the secrets of nature, they recorded their findings from the 1930’s to the 1970’s.

Dr. Albrecht held four degrees – B.A, B.Sc, M.Sc, and Ph.D. from the University of Illinois. He travelled and studied soils in Great Britain, Europe and Australia. During his long teaching and learning lifetime, Dr. Albrecht wrote no less than 445 papers on sound agriculture, and almost all have been reprinted in the world’s major languages.  Follow this link to read Healthy Soils, Healthy People; an article about the work and legacy of William Albrecht.  

True science

Kiwi Fertiliser Company is committed to encouraging farmers to understand the “true science” behind soil testing and fertiliser application.

So what is that true science? Dr. Albrecht emphasised that to be true science, it must be highly repeatable. The soil tests must be highly accurate. If you can’t measure it; you can’t manage it. It manages you. In these circumstances, you are subject to the whims of nature and fluctuating yields, diseases and results.

A worthy soil consultant, working with a truly scientific soil test must be able to differentiate between soils that produce top quality crops and those that don’t; and be able to tell why. Our consultants are all highly trained to do just that, and are committed to improving the situation of each of our clients.

The proof of the pudding is in the eating. You can only prove what is being said here by doing it in the field. In some cases, the complete response may take up to three years to achieve. In most cases, results are evident within a month or two, but almost certainly within the first year. If you still have doubts about the effectiveness of the programme; try it on a small scale, or read the many success stories from around the world. You will not regret it. The results you get will prove; this is true science.

Optimum nutrient usage, optimum soil

Kiwi Fertiliser prides itself on delivering fertility as close as nature intended as practicable. Farmers have been led to believe urea is essential for high production. We contend that is not true. Nitrogen can be sourced from the air by plants if the correct conditions are met. After all, the urea manufacturers obtain nitrogen from the air, convert it to urea, and then sell it to the farmer. To ensure your farm gets free nitrogen, you just have to ensure the following conditions:

  • An appropriate calcium and magnesium percent of soil base saturation
  • Available phosphorus
  • Available iron
  • Molybdenum
  • Cobalt

In our general experience, this is what we find, in relation to the above factors:

  • The vast majority of properties do not have the correct calcium and magnesium percentage. For most properties, on a lab test from Perry Agricultural Laboratories, this should be 68% and 12%. Most properties are either deficient or excessive in Ca and deficient in Mg.
  • Most properties have available P; in fact excess P; a few are deficient, at least on flat land.
  • Iron is variable with most sufficient on the flats, but not necessarily on the hills.
  • Molybdenum is generally in excess.
  • Cobalt is deficient.

We often find higher amounts of nitrogen in our soil tests, than in soil tests taken on farms not using our fertiliser system. That means the nitrogen is where it is supposed to be. It’s in the soil, not in the water.

Our recommended phosphate products are all alkaline. Alkaline P does not have the same propensity to complex in the soil as acid superphosphate does. Further, acid P is harsh on soil fungi. One of soil fungi’s functions is to hold calcium in the soil. Without those fungi, calcium is not held in the soil at all. To make matters worse, urea can take calcium and copper out of the soil. Some fungi increase plants’ ability to uptake P by up to 1000 times. It is a huge loss to lose them.

Potassium is not considered an issue by regional councils. However, since potassium chloride can be harsh on soil microbial life, we only recommend potassium sulphate. The chloride form is the main culprit that hardens soil. Hard soils are dead soils with less humus in them than living, productive soils. When it rains, hard soils shed water much faster than soft, spongy living soils. This leads to erosion and nutrient loss. A soil with 1% organic matter can only retain 20% of the water that a 5% organic matter soil can. That has serious implications in drought situations.

Please Note: Any figures mentioned above are relevant only to those establishments and results will not be the same, or mean the same, if applied to or from other any soil tests.
